Strikes on at two Chilean copper mines

IndustryWeek is relaying a story from Agence France Presse, reporting that workers at two copper mines in Chile have gone on strike. Miners at Codelco's Chuquicamata and Mina Sur mines, which together account for about four percent of the world's copper production, are calling for a 7.5 percent pay hike. Codelco is owned by the Chilean state, which produces around 1.6 million tons of copper per year and employs around 5,600 workers.
